heap

问题 I recently read Bernard Chazelle's paper "The Soft Heap, An Approximate Priority Queue with Optimal Error Rate by Bernard Chazelle" (http://www.link.cs.cmu.edu/15859-f07/papers/chazelle-soft-heap.pdf) The paper talks a lot about "corruption." What is corruption, how do elements get corrupted, and how does it help you? I have spent a lot of time reading through the paper and Googling and this still doesn't make sense. 回答1: In most research papers on priority queues, each element in the queue

问题 I was reading the comments on this answer and I saw this quote. Object instantiation and object-oriented features are blazing fast to use (faster than C++ in many cases) because they're designed in from the beginning. and Collections are fast. Standard Java beats standard C/C++ in this area, even for most optimized C code. One user (with really high rep I might add) boldly defended this claim, stating that heap allocation in java is better than C++'s and added this statement defending the

问题 I wonder if there's a way to figure out if a variable is stack or heap allocated. Consider this: struct SomeStruct; fn main() { let some_thing = Box::new(SomeStruct); println!("{:p}", some_thing); foo(&*some_thing); } fn foo (bar: &SomeStruct) { println!("{:p}", bar); } prints 0x1 0x1 And then struct SomeStruct; fn main() { let some_thing = &SomeStruct; println!("{:p}", some_thing); foo(some_thing); } fn foo (bar: &SomeStruct) { println!("{:p}", bar); } prints 0x10694dcc0 0x10694dcc0 I can

问题 I ran into an interview question recently. no additional info is given into question (maybe default implementation should be used...) n arbitrary sequences of insert and remove operations on empty min heap ( location for delete element is known ) has amortized cost of: A) insert O(log n), remove O(log n) B) insert O(log n), remove O(1) The option ( B ) is correct. We know option (A) is also can be correct but why (B) is a better option. 来源： https://stackoverflow.com/questions/65203302/best

问题 This question already has answers here : malloc in C: same sizeof before and after? (5 answers) Determine size of dynamically allocated memory in C (15 answers) Closed 6 days ago . In this program I have located char pointer. I have located 1 byte of memory in heap. But when I print its size it shows 4 bytes. please help. //CODES// #include <stdio.h> #include <stdlib.h> int main(){ char *ptr; ptr=(char*)malloc(1); printf("The size is %d.",sizeof(ptr)); } 来源： https://stackoverflow.com
